A: AR19/29/49 series router supports the six new interface modules of ESM, DSIC, DMIM, DFIC, VPM and VCPM. ESM Module: A built-in subcard module applied on the mainboard and primarily used for the IPSec encryption module. DSIC Module:Double Smart Interface Card (DSIC) module which occupies two-SIC-wide and one-SIC-high is mainly used for 9-port Ethernet switch module. DMIM Module:Double Multiplex Interface Module (DMIM) which occupies two-MIM-wide and two- MIM-high is mainly used for 24- Ethernet switch module. DFIC Module:Double Flexible Interface Card (DFIC) module which occupies two-FIC-wide and one-FIC-high is mainly used for 24-port Ethernet switch module. Voice VPM and VCPM Module:VCPM is the voice co-processor module, and VPM is the voice processing module. AR19/29/49 series router is fully compatible with the SIC interface module supported by AR 28-09/1x series router; AR29-21/41 routers are partially compatible with AR 28-3x/40/80 series routers supported MIM interface module, with an effective protection for user's investments. Meanwhile, AR19/29/49 series router supports 9-port DSIC interface card and 24-port DMIM interface module as well as 24-port DFIC interface card, with interface density significantly boosted on top of existing products.

Q: Which aspects of availability are enhanced on AR19/29/49 series router?

A: AR19/29/49 series router enhance the equipment and network availability in the following aspects: 1) Backup center and VRRP AR19/29/49 series router provides the backup center and VRRP technology to ensure delivering a backup solution when the communications or devices break down. As a result, it has ensured smooth data communications and effectively boosted network robustness and availability. The backup center supports backup load balancing features. 2) Fully support external storage devices such as CF card and USB flash memory. Use CF card and USB flash memory for multiple system files and configuration files storage to promote system reliability; external storage devices can store large-capacity system log and security log information to facilitate users' backup, browsing and archiving. 3) Support route backup and fast reroute Support Huawei's proprietary dynamic route backup, namely standby of routing, and fast reroute (FRR) technologies. In the event of network failure, it can rapidly recovery links and thus guarantee normal data forwarding. 4) Support power supply module, interface card and fan hot swap AR19/29/49 series router is adopted carrier-class design to support power supply hot backup (except AR1961 and AR2901), and power supply module, FIC interface card and fan frame hot swap which can be removed and replaced without affecting services so as to meet the high-reliability requirements of carrier-class network.

Q: What benefits are delivered through using the new RISC CPU on the Huawei AR19/29/49 series router?

A: AR19/29/49 series router uses the new RISC CPU which dominant frequency has improved to improve the forwarding capability than the former products. In the meanwhile, CPU has a built-in hardware encryption engine which has significantly improved device encryption capability without the encryption interface cards.

Q: What are the VPM and VCPM? What features do they have?Which voice features are available on AR19/29/49 series router?

A: Voice processor module (VPM) supports voice decoding large scale DSP array and is primarily used for voice coding and decoding. Voice co-processor module (VCPM) can be directly configured on the control board and the multi-service board of AR19/29/49 series router and can also be installed on MIM and FIC interface cards. It supports the following features: 1) 2K?2K TDM local switching; 2) High-precision synchronization phase lock of global clock; 3) Fast data transit from SPI bus to memory bus which can avoid from occupying CPU resources and significantly enhance voice data processing performance. AR19/29/49 series router has full consideration for user's practical networking needs, supports the leading voice communications protocols such as H.323 and SIP, provides extensive voice interface types, and is capable of directly connecting to telephone, electrograph and remote switches. As a result, it has delivered top-quality voice and fax communications, and can provide one-stage/two-stage dialing services. AR19/29/49 series router can also interwork seamlessly with other leading vendor's voice gateways and thus effectively protect user's investment. Since AR19/29/49 series router uses a scalable architecture, the digital signal processor (DSP) resources are allocated in a unified way and can be shared with the voice interface module to significantly boost DSP resource availability and increase access density. At the same time, it provides the TDM switching and realizes TDM switch for local users. On the one hand, this can guarantee voice quality; on the other hand, it keeps local call from occupying DSP resources, and has thus saved DSP resources.

Q: What does ESM feature in?Which modules does it support?

A: ESM is a built-in subcard, which does not occupy host slots and can effectively promote host security performance, while ensuring interface density. AR19/29/49 series router currently supports IPSec VPN ESM Module.

Q: Does AR19/29/49 series router support IPv6? How to protect user's existing network investments?

A: AR19/29/49 series router fully supports IPv6 and IPv6 features. It is not only IPv6 Ready but can realize actual IPv6 networking applications as well. At present, it can realize IPv6-only networking, IPv6 island networking with IPv4 networking, IPv4 island networking with IPv6 networking, and IPv4 and IPv6 interworking; Meanwhile, AR19/29/49 series router also supports dual stack and ensures interwoking between IPv4-only devices and IPv6-only devices in the same network. It supports multiple tunneling technologies such as IPv6 over IPv4 GRE tunnel, IPv4 over IPv6 tunnel, 6 to 4 automatic tunnel, IPv4 compatible automatic tunnel, and ISATAP tunnel, and enables users to smoothly migrate from IPV4 network to IPv6 network. As a result, it can protect users' existing investment and is compatible with existing IPv4 networks. Additionally, AR19/29/49 series router also supports more IPv6 features. For detailed specifications, please refer to product specifications.

Q: AR19/29/49 series router supports new storage medium CF card and USB interfaces. Which areas can they be applied in?

A: CF card applications: AR19/29/49 series router provides CF card in default as storage media to replace FLASH storage media on the existing devices in order to store the system file, configuration file and system log file. CF card is scalable up to 1G and can make log information more detailed and comprehensive. Additionally, it also significantly reduces hardware costs, while adding storage space. USB interface applications: AR19/29/49 series router supports USB interfaces, and the router configuration file can be stored in USB flash memory. After insert the USB flash memory storing configuration file in router's USB interface, the router can automatically access or retrieve configuration file from USB flash memory so as to upgrade router configuration file and update router configuration automatically. As a result, it is very practical to carry out "zero touch" configuration deployment. This means that business customers or telecom carriers can load the router's bootstrap configuration file to USB flash memory. With the help of bootstrap configuration file, the remote station can establish connectivity to the main station, then download the complete configuration file and carry out router deployment, thereby resulting in reduction in user's remote deployment costs.

Q: Does AR19/29/49 series router support IPv6? How to protect user's existing network investments?

A: The AR19/29/49 series router is a brand new multi-service integrated router series launched subsequent to the AR series routers. It includes the three series of AR19, AR29 and AR49, and the product portfolio is targeted at a continuum from low end to high end. This product can be used as carrier network or large network's edge access, and branch or enterprise core router.

Q: AR19/29/49 series router's layer 2 switch module supports extensive layer 2 features. So, what benefits has such support brought to customers?

A: Enterprise branch offices can directly access to PCs and voice terminals etc. by using the layer 2 switch module on the AR routers. This approach has saved the use of convergence switches, and simplified the network architecture, while reducing costs. An AR router supports up to 24-port switch module, has the rich layer 2 features of Ethernet switch, and realizes "routing and switching unification" features, while delivering to users a more flexible networking mode.
